Abstract
A positioning device includes an camera, a detector, and a circuit. The camera is mounted on a moving body, and captures an image of surroundings of the moving body to acquire a captured image. The detector is mounted on the moving body, detects motion of the moving body, and outputs a detection signal indicating a detection result. The circuit processes the detection signal using a correction value for correcting a bias error included in the detection signal without depending on the motion of the moving body. The circuit computes the position of the moving body based on the captured image acquired by the camera and the detection signal processed. If the circuit determines that the moving body is stationary, the circuit updates the correction value of the bias error based on the detection signal output by the detector.
